Alpha 5" Snail Lock Adapter — 5/8"-11 (SFAT-5/8)

The hook & loop backed face accepts any 5" Snail Lock wheel — twist on to lock, twist off to release — so grits can be changed in seconds without tools.

- Confirm your grinder/polisher has a 5/8"-11 male spindle and a maximum no-load speed at or below 2,000 RPM.
- Thread the SFAT-5/8 adapter onto the spindle by hand until snug; tighten lightly with the supplied spanner if needed.
- Align the Snail Lock wheel to the adapter face and twist clockwise until it locks into position.
- Run the tool at the wheel manufacturer's recommended RPM (typically 900–2,000 RPM for 5" Twincur EB wheels).
- To change grits, stop the tool, twist the wheel counter-clockwise to release, and snap on the next grit.
- Inspect the adapter and hook & loop face periodically; replace if the locking lugs or pile face show wear.
